Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I'm looking at Fastmail. They pretty much cover everything I want, to the point other features like encrypted storage of mail on their servers and servers located outside the US* are the only things left for me to worry about. Whilst I'm thinking of the a domain name, I'm half considering Easydns, but I really think Fastmail will get my money. I can't see Microsoft making this level of service readily available or at a reasonable price for home usage.
* Fastmail do claim that: "we won't release any data without the required legal authorisation from an Australian court. As an Australian company, we do not respond to US court orders." I'm not sure how they do this give they have servers in NY.
